HT-20A mortar rebound tester

HT-20A mortar rebound tester is used for non-destructive testing of compressive strength of structural engineering sintered ordinary bricks or sintered porous brick masonry mortar

Functional Features

High toughness alloy steel springs have good damping and fatigue resistance;

CNC precision machining of refined movement, confirming stable rebound value

The pointer axis is smooth, with uniform friction and high measurement stability

The precision ground spherical zero adjustment screw is matched with a high-strength hook, making rebound firing smoother and wear-resistant (based on actual reports), and less likely to bounce off

Adopting high-strength and hard aluminum body shell, it is lightweight and resistant to pressure and drop

Customized protective sleeve handle for more comfortable rebound operation

Data processing software that supports raw record input, facilitating the production of inspection reports
